What needs to be paid attention to for SMT patch?

With the development of science and technology, many electronic products are developing in the direction of small and fine, making the size of many SMT patch components smaller and smaller. Not only the requirements of the processing environment are constantly improving, but also the processing technology of SMT patch has higher requirements.Below from the small editor to introduce you in detail SMT chip processing needs to pay attention to which points.

Firstly, when SMT patch is processed, it is known that solder paste is needed.For just purchased solder paste, it must be placed at 5-10 degrees if not immediately used

The solder paste should not be placed below zero in order not to affect the use of solder paste.

Second, during the mounting process, the equipment of the SMT machine must be inspected frequently. If the equipment is aging or some parts of the device are damaged, in order to ensure that the patch will not be slanted and high throwing material occurs, the equipment must be repaired or replaced.Only in this way can we reduce production cost and improve production efficiency.

Third, if we want to guarantee the quality of PCB plate welding during SMT processing, we must pay attention to whether the process parameter setting of reflow welding is very reasonable. If there is any problem in parameter setting, the quality of PCB plate welding cannot be guaranteed.Therefore, it is usually necessary to test the furnace temperature twice a day and at least once.Only by constantly improving the temperature curve and setting the temperature curve of welding products can the quality of products be guaranteed.

It can be said that the technical content of SMT patch processing is very high, in the process of processing must pay attention to these points.If we do not pay attention to these points and just want to improve production efficiency, the quality of the processed products will be wrong and the sales of products will be greatly affected.
